NOTE:

Readings should be taken at approximately 20°C.

Solenoid SLT, SLS and SLU

Measure the resistance between both the pins in the solenoid connector.

Correct value: 5.0-5.6 Ω.

If the value of any of solenoids SLT, SLS and SLU is incorrect

Replace the control system. See Replacing the control system .

The control system is calibrated together with the solenoids.
